Energy Analysis

Calculation Steps

1

Calculate Total Load

Formula:
Qtotal=Qcooling+QheatingQ_{total} = Q_{cooling} + Q_{heating}
Calculation:
Qtotal=50000.00+40000.00Q_{total} = 50000.00 + 40000.00
Result:
90000.00 BTU/hr90000.00 \text{ BTU/hr}
2

Convert Load to Kilowatts

Formula:
QkW=QBTU/hr×0.000293071Q_{kW} = Q_{BTU/hr} \times 0.000293071
Calculation:
QkW=90000.00×0.000293071Q_{kW} = 90000.00 \times 0.000293071
Result:
26.3764 kW26.3764 \text{ kW}
3

Calculate Total Energy Consumption

Formula:
Etotal=QkW×tE_{total} = Q_{kW} \times t
Calculation:
Etotal=26.3764×8760E_{total} = 26.3764 \times 8760
Result:
231057.18 kWh231057.18 \text{ kWh}
4

Calculate Energy Intensity

Formula:
EI=EtotalAEI = \frac{E_{total}}{A}
Calculation:
EI=231057.185000.00EI = \frac{231057.18}{5000.00}
Result:
46.2114 kWh/sq ft46.2114 \text{ kWh/sq ft}
